Why it works: Chocolate and sugar are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 15,404 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Chocolate Biscuits
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the mixture
Mix the chocolate and sugar together.
Moisten the mixture with enough beaten egg white to form a soft paste.
Shape and bake
Spoon small amounts onto a sheet of paper, leaving space between each.
Bake in a moderate oven at 350°F (175°C) for 20 minutes.
Finish
Once baked, turn the sheets over to rest the biscuits on the table.
Brush the paper over the biscuits with a little water to loosen them.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chocolate
- Provides the main flavour and fat, giving the biscuits their rich body.
- Sugar
- Adds sweetness and bulk, helping the paste hold its shape as it bakes.
- Egg white
- Binds the grated chocolate and sugar into a paste that holds its shape and sets when baked.
The step that matters
Brushing the paper with water. A little water softens the dried sugar at the base of each biscuit so it releases from the paper. Too much water can dissolve the biscuits or make them soggy, so use only a light brushing.
